CDN : l'erreur d'échec de la mise à jour du dépôt de tronc se produit

Après avoir exécuté l'installation du pod, j'ai l'erreur suivante :

[!] CDN: trunk Repo update failed - 4 error(s):

Solution:

Remplacez la source cdn par la source 'https://github.com/CocoaPods/Specs.git'

marcher:

1. Ajoutez la source 'https://github.com/CocoaPods/Specs.git' en haut du podfile

2. Exécutez pod repo remove trunk sous le terminal pour supprimer le tronc

3. Re-installation de pod
